zsh completion: disable defaults and verbose output when completing
If ui.verbose is set to True in hgrc, commands used to provide completions
would yield bad results. For example, qpush completion would include the
patch numbers and statuses as returned by qunapplied -v, instead of just
the patch names.
Defaults are also disabled when completing to prevent similar issues when
an option is set that changes a command's output.

Create a copy of an existing repository in a new directory. The
source and destination are URLs, as passed to the repository
function. Returns a pair of repository objects, the source and
newly created destination.
The location of the source is added to the new repository's
.hg/hgrc file, as the default to be used for future pulls and
pushes.
If an exception is raised, the partly cloned/updated destination
repository will be deleted.
Arguments:
source: repository object or URL
dest: URL of destination repository to create (defaults to base
name of source repository)
pull: always pull from source repository, even in local case
stream: stream raw data uncompressed from repository (fast over
LAN, slow over WAN)
rev: revision to clone up to (implies pull=True)
update: update working directory after clone completes, if
destination is local repository (True means update to default rev,
anything else is treated as a revision)
